Recovering Tenant Data

Updated at:Dec 31, 2019 GMT+08:00


Tenant data is stored on MRS Manager and in cluster components by default. When components are recovered from faults or reinstalled, some tenant configuration data may be abnormal. In this case, you can manually recover the tenant data.


  1. On MRS Manager, click Tenant.
  2. In the tenant list on the left, click a tenant node.
  3. Check the status of the tenant data.

    1. In Summary, check the color of the circle on the left of Basic Information. Green indicates that the tenant is available and gray indicates that the tenant is unavailable.
    2. Click Resource, and check the color of the circle on the left of Yarn or HDFS Storage. Green indicates that the resource is available and gray indicates that the resource is unavailable.
    3. Click Service Association, and check the Status column of the associated service table. Good indicates that the component can provide services for the associated tenant, while Bad indicates that the component cannot.
    4. If any of the preceding check items is abnormal, go to 4 to recover tenant data.

  4. Click Restore Tenant Data.
  5. In the Restore Tenant Data window, select one or more components whose data needs to be recovered, and click OK. The system automatically recovers the tenant data.
